Definitions

  • the present invention is directed to blends of certain polymers.
  • the blends are compatible and find many uses such as packaging applications owing to their chemical resistance and toughness.
  • Polymer blends are a route to novel and useful materials having improved properties, such as easier processing, better mechanical properties, chemical resistance and lower cost.
  • blend physical properties may be poor.
  • a compatibilizer whose purpose it is to improve the blend properties.
  • Compatibilizers are typically either random, graft, or block copolymers. Reference is also made to United States Patents 4,885,334 and 4,886,126 for compositions of this general type.
  • a compatibilizer in admixture with a blend of a polyphenylene oxide polymer and a styrene acrylonitrile polymer.
  • the compatibilizer is a block copolymer of styrene and acrylonitrile.
  • Block copolymer compatibilizers for a blend of polyphenylene oxides and a "polar thermoplastic resin", which can be a polyester, are described in United States Patent 4,885,334.
  • the compatibilizer is a modified block copolymer obtained by subjecting a hydrogenated block copolymer comprising an aromatic vinyl compound polymer block (for example, derived from styrene) and a conjugated diene compound polymer block (for example, 1,3, butadiene) to graft polymerization in the presence of a monomer having an epoxy group (for example, glycidyl methacrylate).
  • a hydrogenated block copolymer comprising an aromatic vinyl compound polymer block (for example, derived from styrene) and a conjugated diene compound polymer block (for example, 1,3, butadiene) to graft polymerization in the presence of a monomer having an epoxy group (for example, glycidyl methacrylate).
  • blends of certain polyesters with phenylene oxide containing polymers have brittle mechanical properties.
  • a compatibilizer that, when added to these blends, improves their mechanical properties and allows the potential advantages of these blends--for example, easier processing than phenylene oxide containing polymers, higher thermal dimensional stability than the polyesters alone, and lower cost than phenylene oxide containing polymers--to be realized.
  • a polymer blend composition comprising a polymer that is miscible with polystrene and a thermoplastic polyester wherein the diacid component of said polyester includes aromatic groups and wherein the diol component comprises at least 20 percent by weight of a noncyclic, aliphatic diol, said blend further comprising a copolymer compatibilizer in an amount sufficient to effect compatibility between said polyphenylene ether containing polymer and said polyester, said compatibilizer comprising a copolymer having repeating units derived from an aromatic vinyl compound monomer and a vinylphenol monomer.
  • One component of the blend of the invention is a polymer that is miscible with polystyrene, such as polyphenylene oxide (IV).
  • polystyrene such as polyphenylene oxide (IV).
  • IV polyphenylene oxide
  • Useful polyphenylene ether containing polymers are described, for example in the above referenced U.S. Patent 4,885,334 at Col. 1-Col. 2. These polymers are obtained by the polycondensation of one or a mixture of phenols represented by the formula: wherein R1 represents a lower alkyl group having from 1 to 3 carbon atoms and R2 and R3 each independently represent a hydrogen atom or a lower alkyl group having from 1 to 3 carbon atoms.
  • polystyrene examples include polystyrene, high-impact polystyrene, tetramethylbisphenol-A polycarbonate, poly(vinyl methyl ether), and blends of polyphenylene ethers with polystyrene, and styrene-containing copolymers.
  • One of the components of the blend of the present invention is a thermoplastic polyester wherein the diacid component of the polyester includes aromatic groups and wherein the diol component of the polyester comprises at least 20 mole percent of a non-cyclic, aliphatic diol.
  • the diacid component will be considered to be aromatic if at least 50 mole percent of the diacid is aromatic.
  • mixtures of diacids can be used.
  • Particularly useful diacid components result in repeating units represented by the formula: wherein a is an integer of from 1 to 4 and each R4 is independently selected from the group consisting of hydrogen; alkyl groups having from 1 to 4 carbon atoms, for example methyl, ethyl and t-butyl; and halogen, particularly bromo and chloro.
  • Particularly useful diacid components are derived from acids which include: phthalic acid; isophthalic acid; terephthalic and naphthoic acid.
  • the second component of the polyester is a non-cyclic diol component.
  • the diol component can include up to 80 mole percent of a cyclic component.
  • Useful diol components result in repeating units having the structure: wherein R5 represents a straight or branched alkylene group of from 1 to 10 carbon atoms, for example, ethyl, butyl and neopentyl.
  • diols which can be used up to 80 mole percent include cyclic diols resulting in repeating units having the formula: wherein n is 0 to 2 and a is an integer from 1 to 4 and each R4 is independently selected from the group consisting of hydrogen; alkyl groups having from 1 to 4 carbon atoms, for example methyl, ethyl and t-butyl; and halogen, particularly bromo and chloro.
  • n is an integer from 2 to 4 and m is an integer from 2 to 15.
  • diol components are derived from diols which include: ethylene glycol, butanediol, cyclohexylene dimethanol, 1,2-propanediol and neopentyl glycol.
  • miscible it is meant that the blended polymers form a homogeneous blend that has a single glass transition temperature.
  • amorphous miscible blends are clear. In a typical test for clarity a blend of interest is coated or cast into a thin film. A blend is considered to be clear if ordinary newsprint can be read through the film. Immiscible blends are those that have more than one glass transition temperature or are opaque or show two distinct solid state NMR relaxation times.
  • the term compatible is a more general term typically meaning that the components mix and process without difficulty and have good material properties.
  • polyesters that are useful in the invention can be made by methods which are extremely well known in the art. In fact, many of the useful polyesters are commercially available. Useful polyesters are commercially available from the Eastman Kodak Company under the trade names TENITE®, KODAK KODAPAK®, EKTAR PCTG® and EKTAR HPETG®.
  • the blend of the invention further comprises a compatibilizer.
  • the compatibilizer is a copolymer having repeating units derived from an aromatic vinyl compound monomer and a vinylphenol monomer.
  • the aromatic vinyl compound monomer can be represented by the formula: wherein R6 and R7 are independently selected from the group consisting of a hydrogen atom, a lower alkyl group having from 1 to 6 carbon atoms, a chlorine atom and a bromine atom.
  • Useful vinyl aromatic monomers include styrene, p-methylstyrene, ⁇ -methylstyrene, t-butylstyrene and copolymers.
  • the currently preferred monomer is styrene because it is inexpensive and readily available.
  • the other component of the compatibilizer useful in the invention is a poly(vinylphenol).
  • These polymers include repeating units derived from vinylphenol or derivatives thereof.
  • Useful repeating units are derived from vinylphenol or derivatives of vinylphenol where the hydrogen of the hydroxy group is replaced with a group such as metal ions, silyl or organic groups such as tertiary-butyloxycarbonyloxy (tBOC), alkyl, alkanoyl, and benzoyl.
  • repeating units can be represented by the formula: wherein R8 is hydrogen or methyl and R9 is selected from the group consisting of -OH, -OSi(R10)3 and -OM where M is a metal cation, tBOC, OR10 and OCOR10, where R10 is selected from alkyl groups having 1 to 5 carbon atoms or aryl.
  • M can be any univalent or divalent alkali, alkaline earth or transition metal cation. Non-limiting examples of such cations include sodium, magnesium, calcium, lithium, potassium and zinc cations.
  • the group is not a hydroxy group, it is preferred to convert it to a hydroxy group. That is, the other alternatives to phenol itself are precursors to vinylphenol containing polymers.
  • R9 in the formula above can be located in either the para- or meta- position. It is preferred, primarily for reasons of availability of starting materials and ease of synthesis, that R9 be located in the para- position. Additionally, it is contemplated that, in addition to the R9 substituent, the pendant benzene ring can be substituted with such non-interfering substituents as C1-C4 alkyl, or halogen in one or both meta positions.
  • the styrene-vinylphenol block copolymer compatibilizers can be prepared by the method of Nakahama disclosed in Yuki Gosei Kagaku Vol. 47, pp. 448-456 (1989); American Chemical Society Polymer Preprints , Vol 27, No. 1, pp. 194-5 (1986); and Japanese Kokai 59-53509 (1984).
  • Graft copolymer compatibilizers can be prepared by conventional free radical copolymerization of a methacryl-terminated polystyrene macromonomer and a suitably protected vinylphenol monomer.
  • Poly(vinylphenol) homopolymer and random copolymers(III) can also be prepared by conventional free radical polymerization.
  • the preferred range for the molecular weight of the vinylphenol containing copolymer is between 1,500 and 500,000. Particularly preferred are vinylphenol polymers having a molecular weight between 20,000 and 250,000.
  • the preparation of high molecular weight vinylphenol containing polymers is described in: Frechet and others; NOVEL DERIVATIVES OF POLY(4-HYDROXYSTYRENE) WITH EASILY REMOVABLE TERTIARY, ALLYLIC OR BENZYLIC ETHERS; Polymer Bulletin 20 , 427-434 (1988).
  • thermoplastic blends can be made by methods which are well known in the art. These thermoplastic blends, for example, can be made by mixing powders of the blend components together and then melt extruding the mixture in a screw extruder. In another method, both components are dissolved in a common solvent, for example dioxane, pyridine or tetrahydrofuran, and then precipitated in a non-solvent for both of the polymers, such as for example hexane. In another method, both components are dissolved in a common solvent and solvent cast onto an inert substrate.
  • a common solvent for example dioxane, pyridine or tetrahydrofuran
